Next, I created a histogram with average #nicar18 tweet counts by hour for the three full days: Thursday, Friday and Saturday. It shows when people sent the most tweets — and that they apparently took more breaks during lunch and just before the first afternoon sessions began.

The pattern is also clear here in a more granular view of daily tweet counts by hour:

This tweet volume, which only captures people tweeting with the hashtag, was posted by attendees from across the globe. This year’s conference, as I mentioned in the previous post, had record-breaking attendance: more than 1,200.

Here’s where the attendees came from:

These types of maps are imperfect, of course, especially on mobile. For one, it’s tough to decipher attendance from the Northeast and Mid-Atlantic regions.

Here’s a more focused version (still a little nuclear blasty), if that helps (please note that the scale is different from the map above):

I’m in the United States this week to attend the annual news nerd conference known as NICAR, a diverse gathering of reporters, editors and developers (and others) focused on storytelling with data.

I look forward to it like Christmas.

I get to return to the United States, see old friends, learn new skills and drink Diet Coke, which is nearly impossible to find in South Korea, where I work as a foreign correspondent for the Los Angeles Times.

These basic graphics help explain the event, held this year in Chicago.

First, there’s record-breaking attendance* this year:

The event has more than 200 sessions over five days, from the basic use of spreadsheets in news gathering to the construction of complex news applications — and the organizers (who graciously share data about the conference) categorized them by type:

The conference generally has a mix of skills sets and expertise levels, which is evident in the session categories:

There are people here from almost every American state and from numerous countries around the world. My jet lag brain is still working through how to best visualize that, perhaps in a map. I’ll post something soon.

After attending each year since 2006, I had to skip the convention in 2015 and 2016 because I now live in Seoul. But I’m making the long journey to Florida this year, and I wanted to know how many people would be there.

I’ve been in Raleigh the last few days for the Computer-Assisted Reporting Conference held by Investigative Reporters and Editors (one reason why the ‘viz’ hasn’t exactly been ‘daily’ of late). On Thursday, I gave this presentation with Sanjay Bhatt, a reporter at The Seattle Times:
